The status: Registrar-Lock or ClientTransferProhibited is a setting designed to prevent unauthorized attempts to steal, modify, or transfer your website.
Indeed, during the transfer process, you will need to unlock the domain name in question to ensure the transfer is completed correctly. You can unlock it directly in your client area.
Important:
This option is only applicable to domain names with top-level extensions (.net, .com, .org …). For extensions such as .ma or .fr, you must consult your provider before proceeding with the transfer.
